DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for tangling two yarns with a compressed fluid and piecing the yarns together, and to modifying the binding of the spliced yarns and a piecing device.

[0002] As a conventional piecing apparatus, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 62-240274. This splicing device untwists the ends of two yarns, sets them in a splicing member (yarn splicing hole), and then injects compressed air into the splicing member to entangle the yarn ends. And twisting and piecing. In the piecing device, glue spray nozzles are arranged on both sides of the piecing member, and mist-like glue is sprayed on both ends of the spliced yarn, so that the binding force and strength (Strength) is improved.

[0003]

In the conventional piecing apparatus, since the glue is sprayed only on the outer periphery of the seam of the yarn, the binding between the yarn fibers inside the yarn cannot be strengthened, and the yarn is not sewn. The effect of sufficiently increasing the binding power and strength (strength) of the seam is small. Also, simply spraying the glue increases the amount of glue remaining on the outer periphery of the yarn. If the yarn is wrapped in this state, the seam of the yarn adheres to the yarn of the package, and the yarn breaks when the package is unwound. There is fear. Further, when a mist-like glue is sprayed on both sides of the splicing member, the glue is scattered on the splicing member, which adversely affects the splicing operation. Then, after being wrapped around the package, if it is handled by a heald or a reed of a loom or the like, the glue may be peeled off from the outer periphery of the yarn joint, and the whiskers may be generated at both ends of the yarn joint. The whiskers frequently cause yarn entanglement and yarn breakage in a weaving process by a loom or the like.

An object of the present invention is to provide a yarn seam modifying method and a yarn splicing apparatus capable of increasing the binding force and strength (strength) of a yarn seam by infiltrating a glue into the yarn seam. is there.

[0005]

SUMMARY OF THE INVENTION The yarn seam modifying method and the yarn splicing apparatus of the present invention actively promote the penetration of the sizing agent into the yarn seam, and the adhesive action of the sizing agent allows the sizing agent to adhere to the inside of the yarn. By reinforcing and modifying the binding between the yarn fibers, the binding force and the strength (strength) of the seam of the yarn are increased. Then, by allowing the glue to penetrate into the seam of the yarn and reducing the size of the glue remaining on the outer periphery of the yarn, the yarn can be immediately rewound into the package without the need for a step of drying the glue. Occasionally thread breakage can also be reduced. In addition, since the binding between the yarn fibers inside the yarn has been strengthened and modified,
Even if it is handled by the lead, the generation of mustache can be reduced.

In the piecing apparatus according to the present invention, the seam of the spliced yarn is sandwiched between the presser plates, and the untwisting and twisting of the seam of the yarn are repeated by the reciprocating motion of the presser plates, so that the yarn fiber is formed. When the binding between them becomes loose, the glue is rubbed between the yarn fibers. In addition, by applying a liquid glue to the yarn splice while the yarn pulled out from the spliced portion is held between the presser plates, it is possible to prevent the glue from scattering at the spliced portion. . In addition, by pulling out the spliced yarn from the splicing portion, the yarn is sandwiched by a presser plate, and the glue is rubbed by reciprocating motion of the presser plate. The location where the agent is applied and kneaded can be appropriately selected to one or more arbitrary numbers.

Next, the yarn seam modifying method will be described with reference to FIGS.
A description will be given based on FIG. This yarn seam modification method
This is executed by the piecing apparatus 1 of FIGS.
A series of operations from piecing will be described.

First, the piecing operation is performed by the yarn YB on the bobbin B side.
Is clamped by the thread clamp plate 14, and the package P
The side yarn YP is clamped by the yarn clamp plate 13.
Subsequently, the yarn pulling levers 9 and 10 are moved toward the yarn splicing nozzle 4 and brought into contact with the stopper 49, whereby the respective yarns YB and
YP is inserted into the splicing hole 16 and each of the yarn end cutters 11,
Introduce to 12. Then, by operating the respective yarn end cutters 11 and 12, the yarns YB and YP are moved to the respective yarn clamp plates 14,
Cut to a fixed length from the point where it was kumped in step 13 [FIG.
(A)].

By operating the untwisting nozzles 5, 6 simultaneously with or before or after the cutting operation, the yarn end sides of the yarns YB, YP are sucked into the untwisting nozzles 5, 6 and untwisted. . At this time, the respective yarn pulling levers 9 and 10 are returned in the direction away from the yarns YB and YP, so that the yarn ends of the respective yarns YB and Y are sucked into the untwisting nozzles 5 and 6 by a sufficient length. [Fig. 8
(See (b)). In this way, the yarns YB and YP untwisted by the untwisting nozzles 5 and 6 are in a state where the yarn fibers at the respective yarn ends are parallel to each other as shown in FIG.

After untwisting the yarn ends of the yarns YB and YP, the operation of the untwisting nozzles 5 and 6 is stopped, and the yarn pulling levers 9 and 10 are operated again to thereby obtain the yarns of the yarns YB and YP. Pull out from each untwisting nozzle 5, 6 while guiding the end. At this time, by operating the thread holding levers 7 and 8, each thread YB,
The YP yarn end is positioned in the yarn splicing hole 16 in cooperation with the restriction plates 19 and 20 (see FIG. 8C).

Thus, the yarn ends (untwisted yarn ends) of the yarns YB and YP are set in a state of being overlapped with each other in the yarn joining hole 16 of the yarn joining nozzle 4. Each thread YB, Y
When the yarn end of P is set in the piecing nozzle 4, the ejection holes 18
By jetting compressed air into the yarn splicing hole 16 from the side, the yarn ends of the yarns YB and YP are swirled by the swirling flow of the compressed air, as shown in FIG.
As shown in FIG. 1 (b), entangled, twisted and spliced. Then, the ejection of the compressed air to the piecing nose 4 is stopped,
The piecing operation is terminated by releasing the clamps on the respective thread clamp plates 13 and 14 (see FIG. 8C).

Subsequently, in the operation of the yarn seam reforming, the spliced yarn is captured by turning the clamp lever 51 of the clamp portion 26 toward the yarn splicing nozzle 4 (see FIG. 9A). Further, the thread is clamped (gripped) in cooperation with the lever 51 by rotating the clamp lever 52 toward the yarn splicing nozzle 4 (see FIG. 9B).

In a state where the yarn is clamped by the clamp levers 51 and 52, the clamp levers 51 and 52
By turning 52 toward the rubbing section 25, the spliced yarn is inserted between the presser plates 28 and 29 in the open state. At this time, the yarn is positioned so that both ends of the seam of the yarn face each glue nozzle 31 of the holding plate 28 [FIG. 9 (c)].
reference〕

By pressing the piston 44 of the supply valve 38 with the thread inserted into the kneading section 25 (see FIG. 7), a fixed amount of glue is discharged to each glue nozzle 31 side. As a result, the glue is discharged from the respective glue nozzles 31 onto the surface of the holding plate 28 by an amount that causes tearing (an amount that does not flow through the holding plate 28). Then, by closing the presser plate 29, the thread Y
Is pressed while cooperating with each presser plate 28, and a glue is applied to both ends of the thread joint [FIG. 10 (a), FIG.
(C)). The amount of the glue applied is appropriately adjusted according to the yarn count and type.

Subsequently, the link rod 34 of the massaging section 25
Is moved back and forth, and the link plate 35 is rotated, whereby the holding plate 29 is reciprocated with respect to the holding plate 28. As a result, the spliced yarn is repeatedly untwisted and twisted by the frictional force of the friction sheet 30 and the like, and when the binding of the yarn fibers of the yarn is loosened (untwisting), the glue is interposed between the yarn fibers. It is rubbed and the seam of the yarn is modified. still,
The reciprocating motion of the presser plate 29 is set to the number of times (for example, 6 to 7 reciprocations) that does not damage the fibers of the yarn Y (see FIG. 10B). The number of reciprocating movements of the presser plate 29 is appropriately adjusted according to the yarn count and type.

At the seam of the yarn, the sizing agent penetrates between the yarn fibers inside the yarn, and the bonding between the yarn fibers inside the yarn is reinforced and modified by the adhesive action of the sizing agent. Further, since the sizing agent permeates into the yarn, the sizing agent remaining on the outer periphery of the yarn is reduced (see FIG. 11D). Then, the presser plate 29 is opened again, and clamps (gripping) by the clamp levers 51 and 52 are performed.
Is released, the modification of the seam of the yarn is completed, and the yarn can be rewound to the package P side.

According to the yarn seam modifying method (yarn splicing apparatus 1) of the present invention, the following effects can be obtained.

[0034] By actively promoting the penetration of the sizing agent into the seam of the yarn and strengthening and reforming the binding between the yarn fibers inside the yarn by the adhesive action of the sizing agent, the binding power and strength ( Strength) can be increased. Then, the strength effect of the yarn seam was verified by a tensile test. This tensile test
By pulling the spliced yarn, the strength retention (%), CV (%), and minimum tenacity (g) of the seam of the yarn were measured. The tenacity retention (%) refers to the ratio of the strength of the yarn seam to the strength of the parent yarn (yarn that is not spliced), and CV
(%) Means a yarn unevenness variation coefficient. As test samples, a wool yarn having no glue applied to the seam of the yarn and a wool yarn impregnated with the glue at the seam of the yarn were used.
27.5. Table 1 shows data of the test results.

[0035]

[Table 1]

As apparent from Table 1 above, the yarn in which the sizing agent was impregnated at the seam of the yarn was compared with the yarn which was not coated with the sizing agent.
Strength retention (%), CV (%), and minimum strength (g)
Can be increased.

By infiltrating the glue into the seam of the yarn,
Since the binding force and the strength (strength) between the fibers can be increased, it is possible to reduce beards caused by handling with a heald and a lead of a loom. The beard effect at the seam of the yarn was verified by a handling test shown in FIG. In this handling test, as shown in FIG. 12, the seam of the spliced yarn is passed through the heald 55, and the heald 55 is moved up and down 150 times. Further, as a test sample, a yarn in which no glue is applied to the seam of the yarn and a yarn in which the glue is penetrated (penetrated) in the seam of the yarn are used. As a test result, the appearance of each yarn is shown in FIG. As is apparent, the yarn in which the glue is permeated into the seam of the yarn can suppress the generation of the whiskers as compared with the yarn which is not coated with the glue. Adverse effects can be reduced.

By infiltrating the glue into the seam of the yarn,
Since the amount of glue remaining on the outer periphery of the yarn can be reduced, it is possible to immediately rewind the yarn into the package without requiring a step of drying the glue. Therefore, the process from splicing to winding can be efficiently performed. Further, since it is not necessary to dry the glue on the outer periphery of the yarn, even if it is immediately wound around the package, it does not adhere to the yarn of the package. Therefore, when the yarn is unwound from the package, the yarn does not break. Further, it is not necessary to provide a dryer for drying the glue on the outer periphery of the yarn, and it is possible to increase the binding force and strength (strength) of the yarn joint with a simple structure.

Since the glue is applied as a high-viscosity liquid (paste) directly to both sides of the yarn joint by opening and closing the press plates 28 and 29, the glue is applied to the yarn joining nozzle 4 (yarn). Spattering). Therefore, the piecing operation can be performed in a clean state. In addition, as a material to be applied to the joint of the yarn, a water-soluble adhesive can be used in addition to the sizing agent. Further, if the binding force of the seam of the yarn is performed with a water-soluble adhesive such as a sizing agent, the sizing agent can be easily removed by washing with water in the next step.

In the yarn seam modifying method of the present invention, a method has been described in which a size agent is penetrated into both ends of the yarn seam.
As shown in FIG. 14, by shortening the seam of the yarn by the yarn splicing means 2, the glue may be permeated only at one portion of the seam of the yarn. This is because the infiltration means 3 is arranged at a different place from the splicing means 2 and the spliced yarns are clamped by the clamp levers 51,
This can be achieved by pulling out the yarn from the piecing nozzle 4 by 52 and applying and permeating a glue to the drawn-out yarn. The glue nozzle of the holding plate 28 is provided only at one location so as to face the seam of the yarn. Further, a structure may be employed in which each glue nozzle 31 of the holding plate 28 is opened and closed by a ball valve. At this time, the ball valve is
Are allowed to flow to each glue nozzle 31 and the reverse flow is stopped. This makes it possible to prevent the glue from drying on the holding plate 28.

Next, an example in which the piecing apparatus 1 is applied to an automatic winder 60 shown in FIG. 15 will be described. The piecing apparatus 1 may be applied to a false twisting machine or a ply twisting machine.

The automatic winder 60 shown in FIG. 15 includes a plurality of winding units 62 arranged in parallel, and doffs a package wound up by the winding units 62 by a doffing device (not shown).

Each winding unit 62 rewinds the yarn Y of the yarn supplying bobbin B into a fixed-length wound package P. Each of these winding units 62 includes a cradle (not shown) that grips the winding tube 63, a traverse drum 64 that winds the yarn Y around the winding tube 63 while traversing the yarn Y, and a yarn clearer 65 that detects a yarn defect. The yarn splicing device 1 is provided between the traversing drum 64 and the yarn trap 66.

The piecing means 2 of the piecing apparatus 1
As shown in FIG. 6, the operation is controlled by a cam box 67 (a plurality of cams), and the operation of the infiltration means 3 is controlled by a plurality of cams 68 and a driving motor 69 which are separate from the cam box 67.

The operation of the piecing apparatus 1 is performed by operating the piecing means 2 in the cam box 67 to splice the yarn ends of the respective yarns YB and YP, and then driving the driving motor 69. This is for modifying the seam of the yarn. When the driving motor 69 is driven, the respective cams 68 are rotated, and the respective levers 51 and 52 of the clamp section 26 are operated by the link rods 53 to clamp the spliced yarn Y. It is inserted between the holding plates 28 and 29 in the open state. Subsequently, the supply valve 38 of the glue supply section 26
Is actuated by the link plate 56 to discharge a fixed amount of glue and supply it to the holding plate 28. And
The presser plate 29 is closed and reciprocated by the link rod 35, so that the glue is applied to and penetrates the yarn joint. The holding plate 29 can be opened and closed by a link rod 35. When this series of operations is completed,
After the holding plate 29 is opened and the clamp (grip) of the thread Y by the levers 51 and 52 is released, the driving of the driving motor 69 is stopped.

In the winding unit 62 of the automatic winder 60, after the piecing is performed by the piecing means 2, the glue is applied and permeated to the seam of the yarn in a short time until the yarn is rewound. . And apply glue to the seam of the yarn,
After infiltration, by rotating the traverse drum 64,
The yarn Y is rewound. Thus, the automatic winder 60
When the piecing apparatus 1 is applied to the conventional cam box 6, a plurality of cams 68 separate from the cam box 67 and a driving motor 69 operate the infiltration means 3.
7 can be operated with a simple structure without modification.

[0047]

According to the yarn seam modifying method and the yarn splicing device of the present invention, the permeation of the sizing agent into the yarn seam is positively promoted, and the adhesive action of the sizing agent causes the yarn fibers inside the yarn to intersect. The binding strength and strength (strength) of the seam of the yarn can be increased by reinforcing and modifying the binding.

Then, a glue is penetrated into the seam of the yarn,
By reducing the amount of glue remaining on the outer periphery of the yarn, it is possible to immediately rewind the package without requiring a step of drying the glue, and it is possible to reduce breakage of the yarn when the package is unwound.

Further, since the binding between the yarn fibers in the yarn is strengthened and modified, the generation of mustache can be reduced even if the yarn is handled by a heald or a reed of a loom or the like. Therefore, it is possible to reduce adverse effects such as entanglement and yarn breakage in the loom.

In the piecing apparatus of the present invention, the seam of the spliced yarn is sandwiched between the presser plates, and the twisting and twisting of the seam of the yarn is repeated by the reciprocating motion of the presser plates. When the binding between them becomes loose, the glue is rubbed between the yarn fibers. In addition, by applying a liquid glue to the yarn splice while the yarn pulled out from the spliced portion is held between the presser plates, it is possible to prevent the glue from scattering at the spliced portion. . In addition, by pulling out the spliced yarn from the splicing portion, the yarn is sandwiched by a presser plate, and the glue is rubbed by reciprocating motion of the presser plate. The location where the agent is applied and kneaded can be appropriately selected to one or more arbitrary numbers.
